Remark As in the previous chapter, we must supplement the inclusion of the drift potential with another assumption: for ED to reproduce quantum mechanics the drift potential must have the topological properties of an angle, such that \(\phi \)  and \(\phi + 2\pi \)  can be identified with the same physical state.In the approach taken by Caticha in [1]} one assumes a spherical geometry for the e-phase space so that the angular property of \(\phi \)  is more natural.
